American Full Contact History Lesson

I've mentioned in some old posts how full contact started in the U.S. Karate tournament fighters wanted an outlet to test their skills under a realistic contact method in the 70s. This gave rise to American Full Contact Karate, then American Kickboxing. I came across clip of Joe Corely Vs. Howard Vanderbeck from 1975. Joe was the first big time promoter of kickboxing and is the creator of the Battle of Atlanta (one of the major karate tournaments in the U.S.). http://www.youtube.com/watch?v=8a86gnwgdnU
